When might an IRB waiver of informed consent be granted?

An Institutional Review Board (IRB) waiver of informed consent may be granted when research involves no more than minimal risk to participants. This is grounded in ethical guidelines and federal regulations that allow for waivers when the research poses a low risk to the subjects involved.

Minimal risk is defined as the likelihood and magnitude of harm or discomfort anticipated in the research being not greater than those ordinarily encountered in daily life or during routine physical or psychological examinations. When the potential risks are so low, the IRB may determine that the process of obtaining informed consent is not necessary to protect the participants' rights and welfare, allowing researchers to proceed without formal consent if the research meets specific criteria.

Particularly, this situation often applies in fields such as public health or social science, where researchers may collect data anonymously or through observational methods that do not interact directly with participants in a way that could cause harm or distress. The overarching goal is to balance the need for ethical considerations with the value of the research being conducted.

In contrast, granting a waiver is highly unlikely if the research involves significant risks to participants, as this would negate the very purpose of ensuring their safety and providing adequate informed consent. Therefore, the nature of the risk associated with the research directly influences the potential for an
